If you’ve visited moodle.org today, you’re sure to have noticed something odd about the site. As someone (whose identity I won’t reveal!) messaged me:
Hi Helen, sorry to bother you, but I just logged in, via the Moodle.org front page and the panel on the right of the log in was, mostly, upside down. Weird! I know, I do not drink, nor do I smoke funny green cigarettes (I actually lead a singularly boring existence, apart from when I am Moodling :) ) but I am not imagining it. The blurb between the heading and the “this is not your school web site” was really upside down…
There were several reports of the problem in the Moodle Tracker (MDLSITE-895, MDLSITE-896 and MDLSITE-897), the forums (Everything upside down!! and Is the backwards text an April Fool’s day prank?) and even in Moodle Docs (Forum module revision).
As I posted on this day last year (Moodle 2.0 surprise), Moodle has a history of celebrating April Fools’ day. I hope you all had a laugh at Martin’s little trick!

I like 1. april fools. However this is no fun, when you really need the information
Sawjer, apologies for the inconvenience caused by the upside down text. Everything on moodle.org is now back to normal.
For anyone wondering about how it was done, please see the Down under text filter in the modules and plugins database.
(Hmm, looking at the maintainer of the Down under text filter, perhaps Martin is not the person to blame for the April Fool’s day trick!)
For those of us for whom a Moodle plugin is an overkill, there are many website you can use to convert a single post text upside down.. you could google “upside down text” or use, say, http://udtxt.us/
Anyway, funny april fools joke. lol.
